选取2种新疆循环流化床粉煤灰（CFBFA），采用化学分析、X 射线衍射分析和扫描电镜对其组成和形貌进行表征。采用氯化铁和氯化铝水溶液对 CFBFA 进行改性，考察改性 CFBFA 的粒径及投加量对新疆克拉玛依油田三采聚驱油水分离废水处理效率的影响。结果表明，CFBFA 中 SiO2、A12 O3、Fe2 O3、CaO 和 MgO 占总质量的90％左右，其玻璃相含量较低，颗粒形状多数不规则，表面粗糙；粒径≤0．074 mm 的改性 CFBFA 对油水分离废水中油的去除效果最好；随着粉煤灰投加量的增加去油率上升，投加量达0．1 g/mL 时去油率达90％以上。

The composition and morphology of two kinds of circulating fluidized bed fly ash (CFBFA) in Xinjiang were investigated by X-ray diffraction, scanning electron microscope and chemical analysis methods.The CFBFA were modified by adding FeCl3 and AlCl3 water solution, the particle size and dosages of these modified CFBFA on the treatment efficiency of oil-water separation wastewater from Xinjiang Karamay polymer flooding oilfield were also investigated.The experiment results showed that these CFBFA has the contents of SiO2 , Al2 O3 , Fe2 O3 , CaO and MgO accounting for more than 90% of the total weight, lower content of glass phase, irregular particle shape and rough surface; the particle size of the modified CFBFA below 0.074 mm with good removal effect, the removal rate increased with the increasing of the dosage; when the dosage was 0.1 g/mL in the wastewater, the removal rate reached more than 90%.
